--no-threads flag was used, because LLD had deadlock long time ago.
This flag is removed from LLD (in favor of --threads=N) and it looks
like that the bug is gone now. So we can just drop --no-threads flag!
Recent versions of LLVM complain when caller and callee have
different vector attributes: https://reviews.llvm.org/D82562.
To mitigate this problem this commit changes how we include
polyHashUnroll* and polyHashTail into Traits: we duplicate them
inside each trait with correct attributes by using
```
#pragma clang attribute push(ATTRIBUTE, apply_to = function)
```
This solution is not pretty for sure, but Clang is not complaining
anymore.
This commit is important for several reasons:
1. Finally, LLVM update from 8.0.0 to 11.1.0
At the time of writing, LLVM 12.0.0 already came out, but we need to be
compatible with LLVM from Xcode 12.5, so that's why we stick to a bit
older version of LLVM.
2. These LLVM distributions are built with tools/llvm_builder/package.py
We finally managed to introduce an explicit process of building our LLVM
distributions, so we will be able to updated them more frequently and
adapt to our needs.
3. Native Windows LLVM instead of MinGW
Last but not least, we now use native Windows LLVM distribution. While
it might be harder to use (no more posix everywhere), simpler build
process (building msys2 is not that easy) and no need for MinGW-specific
patches makes such distribution way more convenient.
The next LLVM version will be 11.1.0, and we need to be sure that
Xcode supports bitcode of this version. So we bump minimal Xcode version
to 12.5, which should be OK, because by the time Kotlin 1.6.0 comes out,
Xcode 12.5 will be around 6 month old.
Also this commit simplifies tarball naming.
Implemented `test multiple cinterops with test source sets and compilations`
This test will assert source set dependencies
and shared native compilations.
^KT-47775
^KT-47053
^KT-47775 Verification Pending
This implementation will be lenient toward the common
*Test.dependsOn(*Main) mistake.
^KT-47053 Verification Pending
Support source sets that do not have a dedicated
shared native compilation. Also support additional visible source sets
coming from associate compilations.
Now each test is just a sequence of any number of different steps. There
are two kinds of steps:
1. Run some facade
2. Run handlers of specific artifact kind
Through the test each module passed to each step (if it is compatible
by kinds of artifacts)
Adapted existing `test KT-47641 commonizing c-interops does not depend on any source compilation`
to add a project dependency from a project with c-interops (p2)
to a project without any c-interops (p0)
This leads to compilation of project p0, since the
cinteropApiElements configuration was not created on p0
